If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
How much mercury is considered toxic?
When the urine mercury concentration exceeds 100 μg/L, neurological symptoms can develop, and the level of 800 μg/L or above can be fatal. Organic mercury such as methylmercury is usually excreted to the feces.
Why is mercury toxic?
Elemental mercury as a vapor has the ability to penetrate the central nervous system (CNS), where it is ionized and trapped, attributing to its significant toxic effects. Elemental mercury is not well absorbed by the GI tract; therefore, when it is ingested (eg, thermometers), it is only mildly toxic.
Can you handle mercury with bare hands?

Can you drink mercury?
Background: The oral ingestion of elemental mercury is unlikely to cause systemic toxicity, as it is poorly absorbed through the gastrointestinal system. However, abnormal gastrointestinal function or anatomy may allow elemental mercury into the bloodstream and the peritoneal space.
Is mercury legal to buy?

How much mercury is toxic from a thermometer?
